JAMES M. SHEW, OF PAPER MILLS, ASSIGNOR OF ONE-HALF TO GEORG W. S. HOFFMAN, OF BALTIMORE, MARYLAND.

OILER.

SPECIFICATION forming part of Letters PatentNo. 240,045, dated April '12,. 1881.

Application filed February 17, 1881 To all whom it may concern: Be it known that I, JAMEs M. SHEw,'of the village ofPaperMills, county of Baltimore, and State of Maryland, have invented a new and useful Improvement in Oilers, of which the following is a clear, full, and exact description, reference beinghad to the accompanying drawings, making a part of thisspecifieatiom'in which the figure represents a longitudinal section of the nozzle with my improvements attached. My invention relates to oilers in which it is desired to feed out a fixed quantity of oil, and the quantity to be fed is determined by the capacity of the nozzle to feed it; and it consists in the combination of devices, as hereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, I will proceed todescribe the exact manner in which I have carried it out.

Oil-feeders intended to deliver oil or other liquid for filling lamps or lubricating the moving parts of machinery consist, essentially, of a reservoir constructed of metal, hard rubber, or other suitable material, and a conical spout or nozzle, straight or curved, the aperture of which is madeof the right size to deliver the proper quantity of oil required, in many cases so small an amount of oil being required and so small the aperture of the nozzle in the oilfeeder that when the cup is inverted the oil issues from the spout slowly and by drops. So long as the aperture at the end of the spout remains of the original size the amount of oil or other liquid lubricant that flows through it is limited, and there can be but little waste; but as soon as the aperture of thespout becomes enlarged by intentional tampering with it, or by accidental breaking off of the conical end, the oil can be no longer used economi- (No model.)

cally, as, owing to the increased size of the aperture, more oil will flow out than is required for the purpose of lubricating.

"triple, or compound nozzle, formed by fastening together two or more nozzles, one within.

the other, the discharge-points being at a distance of one-half an inch (more or less) from each other. The oil, before it issues from the exterior aperture, must pass from the reservoir through the one or more concealed nozzles, the apertures of which are all of the same size as the exterior aperture. that if the extreme end A ot'the compound nozzle is broken oft, thereby increasing the size of the aperture farthest from the reservoir, no more oil can flow out of it than previously, because the supply is limited by the action of the interior nozzle, B.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A compound nozzle for oilers, consisting of the interior spout, B, secured to the mouth of It therefore follows the oiler, in combination with one or more external spouts, A, of the same delivering capacity and rigidly attached thereto, substantially as shown and described, and for the purpose set forth.
